Gardner goes 3-for-3 in place of Granderson
Roberts and Markakis, the two most senior Orioles, were injured and missed the team's first postseason appearance in 15 years. Matusz, who was reinvented as a left-handed reliever last August, started and allowed two hits to a Yankees lineup that featured only two regulars - center fielder Brett Gardner and catcher Francisco Cervelli.
Gardner had three hits for New York, which lost Curtis Granderson on Sunday for 10 weeks with a broken right forearm.
Left fielder Nate McLouth drove in two runs for Baltimore.
